In 1964, Arthur F. Wightman named the range and peaks after noting that the previously unnamed peaks lay near the source of North Pole Stream, hence this sub-range of the Appalachians has been named after the Christian holiday of Christmas.

Until the mid-1990s, the Christmas Mountains remained untouched by industrial forestry operations. As Crown land, the New Brunswick Department of Natural Resources administered the property as part of a vast swath of forest across the north-central part of the province. With few roads leading into the area, the Christmas Mountains maintained an old growthAcadian forest that was unique to northeastern North America.

New Brunswick Department of Natural Resources leased the property comprising the Christmas Mountains to a U.S. owned pulp and paper company Repap (the name is the word "paper" reversed). Repap began building logging roads into the region around 1995 and began an aggressive clearcutting operation over the next several years, despite numerous vocal and radical protests by New Brunswick-based environmentalists who feared the consequences of habitat destruction and the loss of the old growth forest. Despite the efforts, the Christmas Mountains old growth forest was largely logged by the end of the decade.[7][8][9][10][11][12]
